X155CrVMo12-1 Steel

Subject to size suitability and availability pieces can be produced as ground flat stock in approximately 3 to 4 weeks. Standard and non-standard sizes can be made.

Heat the steel slowly and uniformly to 700°C then more rapidly to 900-1040°C. After forging slow cool.

X155CrVMo12-1 is supplied in the annealed and machinable condition. Re-annealing is only necessary if the steel has been forged or hardened. To anneal, heat slowly and uniformly to 900°C. Soak for up to three to four hours and then allow to cool in the furnace. Re-heat to 800-1040°C and again soak for three to four hours. Allow the steel to cool in the furnace.

If heavily machined, ground or otherwise subjected to cold work, the relief of internal strains it is advisable before hardening to minimise the possibility of distortion. Stress relieving should be carried out after rough machining. To stress relieve, heat the steel to 600-650°C. Soak well and cool in the furnace or in air.

It is preferable to heat the tools in a controlled atmosphere. If this is not possible, pack hardening is recommended. A reducing atmosphere is desirable. Pre heat X155CrVMo12-1 steel up to 750-800°C. and allow enough time to soak at this temperature. The temperature should then be brought up to 1020-1040°C for air cooling, or 980°C for oil quenching. Soak thoroughly at temperature for thirty minutes per 25mm of ruling section, then cool or quench accordingly.

Tempering should be done with the minimum possible delay after hardening and preferably when the tools are still hand warm. Select a suitable tempering temperature, bearing in mind the service requirements. Heat slowly and uniformly. When the component has reached the desired temperature, soak for at least sixty minutes. The second tempering should be a repetition of the first. Double tempering of Double tempering of X155CrVMo12-1 is recommended.
